When viewing a painting that is behind glass, one is often affected by the light that is reflected off the front of the glass called glare, which can make it difficult to see the painting. One solution is to coat the outer surface with a film to cancel part of the glare. If the glass has a theoretical refractive index of 1.5 and you use TiO2 film which has a theoretical refractive index of 1.3, what is the minimum film thickness that will cancel light of wavelength 300 nm?
